Googles Green Data Centers - Sustainability + Efficiency = Green Success
While the number of commodity computers that Google has built is a closely guarded secret, the company maintains that the machines, and the dozens of data centers all over the world that house them, are necessary to help organize the world's information through Google's search and other Internet applications. eWEEK looks at Google's method for maximizing computing power while conserving energy in this slide show.
This graph from Google illustrates how Google data centers, including the servers inside, use far less energy than a typical data center. Google has published for the first time a five-step plan for creating energy-efficient data centers.
